Rosin Core Solder Wire for Electrical Soldering(0.8mm/50g),By JWOWO

Used this for a few small electronics projects and it worked great. It melts clean, flows well, and the rosin core makes for easy connections without a lot of mess. No weird smoke or smell either. Definitely good quality for the price. Would buy again.

This is a great solder for the price. But I've never used 63/37 solder, only 60/40. I experienced a problem, although I can't determine what the cause of the problem was. In my case, on a new circuit board I was soldering, the JWOWO solder climbed up my electrical parts, effectively soldering them, but not wetting out and making a connection to the clean and new PCB circuit board.So, comparing this to Radio Shack and also X-Tronic standard 60/40 solders that have about 2% Flux (X-Tronic is listed at 1.8% Flux and 60/40 ratio of lead) the 63/37 JWOWO had some problems. It may not be the solder that is the problem. But I wanted to report it, nonetheless.I've never seen any of my solders (not even the really bad no-name stuff from Harbor Freight) that didn't stick to a circuit board. I had to actually use the X-Tronic solder because on several solder joints, the JWOWO solder would rapidly wet out and cover a transistor, but none of the solder would actually go onto the PCB. It may have been a temperature problem.It may have been something I did wrong. But I have never seen solder actively resist and not wet out or "tin" a clean PCB that was freshly cleaned with 90% isopropyl alcohol.My advice is to try this, and use it for a specific application. But test it first.I will definitely keep using this solder on copper and tin plated wires, because it flows out beautiful, and works perfectly on wire connections. Just test the solder first, and make sure it works well with the alloys you're soldering.In the future, I'm going to switch to Kester 44 63/37 solder with 3% flux (heavier amount of flux) and see if that makes any difference on the small circuit boards. The JWOWO is 2% flux.

Great quality solder. And great price

Very decent solder for the price. It flows well enough, and the flux is very easy to clean with just soap and water.Compared to more expensive 63/37 I have used, it's fine enough. Real good stuff will melt like butter the second it touches the tip of of your iron, and while this stuff is decent, it doesnt quite nail that perfect melt.But it's cheap and you can buy it less than a pound at a time. So I'm going to keep buying it.Solid 8/10 usability.Solid 9/10 price.10/10 clean ability.

This small diameter solder is well packaged, includes internal flux, and should be on-hand for soldering of small electronic parts. Easy to use with 20 to 40 watt soldering iron - not a good idea to use with a hotter iron. A solder wick and even extra flux will be usable too - especially if some un-soldering is needed. A must have item if working with electronic devices.

Works great on soldering wires!

I use it to solder guitar electronics. Melts easily and flows like it should. I would buy again

works as exapected easy to remove and easy to clean and stick well
